Old Omega speedmaster identification and advices

Looks like a 105.012-66 by the shirt pushers and wide T Swiss Made T.

It appears in largely original condition albeit we only have one picture to go on so side and rear pictures would help.

It’s definitely a 105.012 though I don’t see enough to narrow it down to 66 just yet, although it likely is - just flip it over. One bevel on the case back it’s a 66, two bevels it’s earlier.

It is a lovely looking thing to me, used but attractively patinated. The bezel is poor, but who cares, it is what it is. What I mean by that it looks like the original bezel and fits with the watch.

when servicing my instructions would be to service the movement, polish the crystal, and do not replace anything else - most especially the pushers, hands dial and crown. Do not polish any part of the case, just clean it all.

tell him not to try to do anything to those pushers which are press fit, and the heart of the attraction of this reference, apart from the usual speedmaster points.

A beautiful inheritance. This is a piece to treasure.

Find a good independent watchmaker who specializes in vintage Omega and can give the watch a sympathetic service that will help to retain the watch's vintage character. If you can tell us where you're located, we might be able to recommend a watchmaker for you.

That case looks lovely!
Listen to Spacefruit. Do not polish! You will not be allowed back on here!!

with all the customs troubles involved after brexit? 😕 Better to stay in the EU

Exactly. I assume there will be dozens of options in France alone

Based on the marks in the notches in the case back, it’s been opened previously.
